Panerai does not sell parts to independent watchmakers >>

If they need generic parts for the 6497-2 it should not be a problem because these are readily available. If they need parts that are specific to Panerai then you run into issues.

If you want to have the watch serviced by Panerai you can specify that the dial and hands should not be replaced but this can sometimes be a problem if the tritium is starting to flake or crack. Before leaving your watch for service be very specific and put into writing what you do/do not want done and have the AD confirm with Panerai whether they can accommodate you. I would also recommend taking accurate photos of the watch to document it's condition before releasing it to service.
